Prediction of turbulent velocity profile in couette and poiseuille flows from first principles.
To obtain the turbulent velocity profiles in Couette and Poiseuille flows between parallel walls, we use statistical mechanics of point vortices. Our theory does not contain phenomenological constants. The only parameter taken from experiments is the total kinetic energy of the flow. We solve numerically the equation for averaged flow and show that the theoretical predictions are in good agreem...
متن کاملOn scaling the mean momentum balance and its solutions in turbulent Couette–Poiseuille flow
The statistical properties of fully developed planar turbulent Couette–Poiseuille flow result from the simultaneous imposition of a mean wall shear force together with a mean pressure force. Despite the fact that pure Poiseuille flow and pure Couette flow are the two extremes of Couette–Poiseuille flow, the statistical properties of the latter have proved resistant to scaling approaches that co...

15 صفحه اولan investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation
the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
